HUNTINGTON BEACH, Calif. -- (KTLA) -- A woman was arrested Thursday after a fiery crash killed three Las Vegas teens and shut down a portion of the Pacific Coast Highway in the early morning hours, according to authorities.

A northbound white Hyundai Sonata rear-ended a red Toyota stopped at the intersection of PCH and Magnolia Street early Thursday, Huntington Beach police said. Crews, who responded shortly after 1 a.m., discovered one of the vehicles on fire and extinguished it.

At least one person died at the scene and another was transported to a trauma center, according to police. Huntington Beach Officer Angela Bennett later said that three individuals died from the crash.

The fourth victim is in stable condition and expected to survive.

Investigators have not yet identified the victims, describing them only as three young Las Vegas residents who were in Southern California for their spring break.
